Process Control articles
In this paper the use of internally generated stainless steel scrap is discussed. Internal scrap usage and internal scrap substitution with purchased alloys or purchased scrap is examined in the industrially proven UTCAS® converter automation system.
In this paper it is highlighted how the simulated steel making process generates value and it is discussed how this value can be measured. Special applications in process development, training and investment evaluation are presented and practical examples are used to illustrate how value is created.
By implementing a converter downstream of the reduction furnace it is possible to broaden the product range significantly. In this paper some process alternatives and their economical, practical and environmental implications are studied using process models developed based on UHT’s long experience in stainless steelmaking, stainless steel process control and charge chrome refining.
In this paper the UTCAS® process control solution for AOD converter refining is presented briefly and its ability to optimize business while considering environment is high-lighted. The value and benefits to the steelmaker and the environment are illustrated by practical examples from simulated cases.
In this paper different FeNi and FeCr compositions are discussed and their merits for stainless steelmakers in different situations are compared.
In this paper, the real time AOD process control system UTCAS is presented briefly with a focus on its ability to control and optimize cold material additions throughout the AOD refining cycle. In order to emphasise the benefits of this ability, different scenarios are discussed and evaluated.
The UHT Converter Automation System, UTCAS®, is a highly sophisticated computer system especially designed and developed for converter refining processes. The UTCAS® concept combines effective real-time process control system with advanced tools for process design and production evaluation, thereby providing the complete solution for converter process management.
